FitSimp

Give every workout its own look. Explore 183 exercise illustrations and choose from 21 equipment icons, with flexible templates and clear training history.

FitSimp is the most customizable gym app — built by a gym-goer who got tired of bloated logs and rigid templates. Every screen exists to make logging fast and your routine yours.

FOR EVERYONE WHO TRAINS

First-week beginners, intermediates chasing PRs, returners getting back into it, lifters and mixed-modality gym-goers alike. The visual system leans industrial because that's what depth users want. The voice meets you where you are.

BUILT BY A GYM-GOER

FitSimp is made by someone who actually trains. Every feature shipped because it solved a real problem under a bar — not because a roadmap said it should. If you've ever fumbled with a log between sets, this app is the answer to that exact frustration.

SEE WHAT YOU TRAIN

• A full-body anatomical muscle map, front and back
• Recovery view colors each region by how recovered it is, so you know what's ready to train
• Exercise and template views highlight exactly which muscles a session targets
• No more guessing from text labels — glance and go

DEEPLY CUSTOMIZABLE

• Three themes — Crimson, Warzone, Neon Grind — each with light and dark variants
• Per-template identity icons and a 10-color identity palette
• Build templates exactly how you train: any exercises, any order, your own rest intervals
• Lock Screen widgets and Live Activity layouts that fit your routine
• Pick the look that matches your gym; pick the layout that matches your training
